Abstract
The needle valve shunting heat that the utility model relates to a kind of improvement is chewed, comprise needle, valve needle cover, runner plate and heat chew body, be provided with heat bottom runner plate and chew body, runner plate chews in body with heat the needle sleeve pipe being provided with and being communicated with, needle is provided with in needle sleeve pipe, needle chews the valve needle cover of body upper end through being arranged at heat, and contact with the cast gate that heat chews body lower end, charging aperture is provided with near needle sleeve pipe place, the needle sleeve pipe that end and the heat of charging aperture chew body is communicated with, cast gate lower end is connected with the spreader being provided with multiple runner, the exit that each runner is corresponding is connected with gum outlet.Advantage is: effectively solve and cause valve needle cover to walk causing the stuck or bending leakage glue situation caused of needle, substantially increase production efficiency; Cast gate place is connected with the spreader of multiple runner, and a heat is chewed can carry out filler to multiple mould simultaneously, accelerates operating efficiency.
Description
Technical field
The utility model relates to heat and chews technical field, and the needle valve shunting heat particularly relating to a kind of improvement is chewed.
Background technology
At present, the shaping middle injection moulding of Chinese market plastic cement products has occupied very important position, and injection moulding is mainly divided into cold runner and hot flow path, and injection heat is chewed and is mainly used on hot flow path
Now traditional heat is chewed, valve needle cover is positioned on runner plate, because runner plate expands with heat and contract with cold, valve needle cover can be caused to walk, thus cause needle stuck or play go, cause leaking glue, have a strong impact on production efficiency, and charging aperture inlet design unreasonable, easily make material leak, and simultaneously a heat is on the market chewed and can only be carried out filler, inefficiency to a mould simultaneously.Therefore, a kind of new technical scheme should be provided to solve the problem.
Utility model content
The purpose of this utility model is: provide a kind of needle valve of improvement to shunt heat and chew.
For achieving the above object, the technical solution adopted in the utility model is: a kind of needle valve shunting heat of improvement is chewed, comprise needle, valve needle cover, runner plate and heat chew body, be provided with heat bottom runner plate and chew body, runner plate chews in body with heat the needle sleeve pipe being provided with and being communicated with, needle is provided with in needle sleeve pipe, needle chews the valve needle cover of body upper end through being arranged at heat, and contact with the cast gate that heat chews body lower end, charging aperture is provided with near needle sleeve pipe place, the needle sleeve pipe that end and the heat of charging aperture chew body is communicated with, cast gate lower end is connected with the spreader being provided with multiple runner, the exit that each runner is corresponding is connected with gum outlet.
The import department of charging aperture is abducent choana.
Heat is chewed outside body and is arranged with heater wire, and described heat is chewed between body and heater wire and is provided with temp.-sensing wire.
Due to the application of technique scheme, the utility model compared with prior art tool has the following advantages:
In the utility model, effectively solve and cause valve needle cover to walk causing the stuck or bending leakage glue situation caused of needle, substantially increase production efficiency; The import department of charging aperture is abducent choana, expands the scope of charging, avoids the generation of Lou material situation; Cast gate place is connected with the spreader of multiple runner, and a heat is chewed can carry out filler to multiple mould simultaneously, accelerates operating efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment one structural representation.
In above accompanying drawing: 1, needle, 2, valve needle cover, 3, runner plate, 4, heat chews body, 5, needle sleeve pipe, 6, cast gate, 7, charging aperture, 8, runner, 9, spreader, 10, gum outlet, 11, heater wire, 12, temp.-sensing wire.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment one:
As shown in Figure 1, the needle valve shunting heat of a kind of improvement of the utility model is chewed, comprise needle 1, valve needle cover 2, runner plate 3 and heat chew body 4, be provided with heat bottom runner plate 3 and chew body 4, runner plate 3 chews in body 4 with heat the needle sleeve pipe 5 being provided with and being communicated with, needle 1 is provided with in needle sleeve pipe 5, needle 1 chews the valve needle cover 2 of body 4 upper end through being arranged at heat, and contact with the cast gate 6 that heat chews body 4 lower end, charging aperture 7 is provided with near needle sleeve pipe 5 place, the needle sleeve pipe 5 that end and the heat of charging aperture 7 chew body 4 is communicated with, cast gate 6 lower end is connected with the spreader 9 being provided with multiple runner 8, the exit of each runner 8 correspondence is connected with gum outlet 10.
The import department of charging aperture 7 is abducent choana.
Heat is chewed outside body 4 and is arranged with heater wire 11, and heat is chewed between body 4 and heater wire 11 and is provided with temp.-sensing wire 12.
In the utility model, effectively solve and cause valve needle cover 2 to walk causing the stuck or bending leakage glue situation caused of needle 1, substantially increase production efficiency; The import department of charging aperture 7 is abducent choana, expands the scope of charging, avoids the generation of Lou material situation; Cast gate 6 place is connected with the spreader 9 of multiple runner 8, and a heat is chewed can carry out filler to multiple mould simultaneously, accelerates operating efficiency.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
